TDKR wasn't even the first adaptation that had him quit. That was the whole basis of Batman Beyond.

Ah, Batman Beyond. The show, in my opinion, is the only Batman story to have achieved the impossible since Batman's first inception in 1939. It managed to turn Batman into a mantle that can be passed down to someone from a younger generation while still staying 100% true to the idea that only Bruce is the true Batman.

Again, people are taking the idea of Bruce quitting out of context. There is a world of difference between Bruce hanging up the cape & cowl in The Dark Knight Returns/Batman Beyond and him doing it in The Dark Knight Rises.
